What visibility is required for a category B airplane LPV approach when the MALSR are out of service?

• A. 3,000 RVR
• B. 1,500 RVR
• C. 4,500 RVR
• D. 2,000 RVR

Answer: (C)

For a category B airplane conducting an LPV (Localizer Performance with Vertical guidance) approach, the recommended visibility requirement when the MALSR (Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights) are out of service is 4,500 RVR (Runway Visual Range). This standard is established in the operational guidelines to ensure that pilots can adequately see and identify the runway environment during these critical approach phases, especially when an important visual aid like the MALSR is not available to assist with lateral and vertical guidance. Having a visibility of 4,500 RVR provides adequate conditions to support safe landings and ensure that the aircraft has a clear visual reference during the approach and landing process. This requirement is designed to enhance safety by ensuring pilots can adequately assess their surroundings during low visibility scenarios.
